> Above is an API to return series data for number of active nodemanagers in
> the asked time interval. Although the cluster has only 1 nodemanager
> installed, a specific datapoint had 2 as a value which is incorrect.
> *NOTE: Since there is only 1 nodemanager installed, the valid set of values
> at any time is \{0,1\}.*
